SWINGING WINDOW.

Application filed February 23, 1909.

To all whom it may concern:

Be it known that I, CHRISTIAN CASSLE- MAN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Impmvement in Swinging Windows, of which the following is a specification.

This invention relates to the construction of devices for hanging windows which are adapted to both slide vertically and to swing upon pivots at their side.

One of the main objects of the invention has been to devise means whereby existing sliding windows may be adapted to swing, so that they can be opened either by sliding or swinging as preferred.

The nature of my improvements is fully disclosed in the description given below, and the same are also illustrated in the accompanying drawing, in which Figure 1 is an elevation of a window partly broken away, to which my improvements have been applied. Fig. 2 is a detail section of the fastening for securing the window stops. Fig. 3 is a horizontal section of the window showing both sashes as closed. Fig. 4 is a horizontal section showing the sashes as swung partly open. Fig. 5 is a detail elevation of one of the hinges. Fig. 6 is a plan of one of the pintles and its support. Fig. 7 is an elevation of the upper pintle socket of the upper sash and its supporting bracket. Fig. 8 is an elevation of the same showing a side view. Fig. 9 is an elevation of the lower pintle socket of the upper sash.- Fig. 10 is a plan of the upper pintle socket, and Fig. 11 is a similar view of the lower pintle socket of the upper sash. Fig. 12 is a section of the sash weight cord.

In said drawing, 13 is the lower sash and 14: the upper sash of a window provided with my present invention. Both sashes are adapted to slide vertically in the ordinary manner, being attached to sash weights by cords 15 and 16 and they are also intended to swing horizontally being enabled to do so by providing the lower sash with my invention now to be described, and providing the upper sash with pintles and sockets as also to be described. In the case of the lower sash, the sockets 17 and 18 which receive the pintles are movable into and out of acting position, and they are alike except in one respect hereinafter mentioned. To permit this shifting of position I form them Specification of Letters Patent.

upon the ends of sliding plates 19 which are held in keepers 20 secured to the sash frame by screws 21 and The edges of the keepers are doubled over so as to confine the plates as shown at 23, 24. and 25 and the screws 21 pass entirely through openings in the sliding-plate and bear upon the keepers. Attached to each sliding plate is a raised locking plate 27, adapted to engage with the end of the turned over edge 25 of the keeper, and also to enter the notch 28 cut in said turned over edge. The sliding plate is capable of a slight vertical movement so as to carry said plate 27 into its locking positions in one of which the socket will have been positioned to receive the corresponding pintle on which it is to swing, and in the other of which the socket is in the non-acting position which it occupies when the sash is used as a sliding sash. A spring 29 is secured under the edge 23 of the keeper upon a rivet 80, and presses upon the upper edge of the sliding plate, and holds the plate so that its locking device 27 is prevented from escaping from the one of its two locking positions in which it may have been positioned. The sockets 17 and 18 are adapted to engage the pintles 31 and 32 respectively, such pintles being stationarily attached to the window frame as shown. The sliding movements of the socket carrying plate are limited by the rivet 30 in conjunction with cut out portion 26 of the plate. The upper sashes are provided with sockets 33 and 34L and both of which may be stationary upon the sash and they engage pintles 84:0, (but one of which is shown) upon the window frame.

To permit the easy detaching of the weight cords 15 from the sash, I place them in open slots 37 in the sash, and enlarge such slots at the bottom as shown at 38, and form on the end of the cord an enlargement 89 adapted to engage the enlargements 38 in the sash. The enlargement in the cord are obtained by inclosing its end in a hollow metallic bell 4:0, and then forcing a wood screw ll longitudinally into the cord within the bell so that the cord expanded against the bell, and the latter becomes firmly wedged in its position on the cord. This construction enables the user to detach the cords from the swinging side of the sashes instantly, and to reattach them as quickly. I also prefer to provide over the pulleys of llO the cords on the swinging side of the sashes, curved guides 42, between the sides of which and the rim of the pulleys the cords may be engaged with sufficient firmness to hold the weights in the positions they may occupy at the time the cords are detached from the sashes. This is readily done by pulling the cord sidewise so that it is forced into the side narrowing opening between the guides and the pulleys. I also provide the stop 44 at the outside of the lower sash with improved fastenings adapted to facilitate the taking out and putting back of the stop. These fastenings consist of a thumb screw 45, a guiding plate 46 screwed to the outside of the stop and a bushing 47, coarsely threaded on the outside so it may be securely inserted in an opening formed in the window frame under the stop, and finely threaded interiorly so it may be engaged by the screw 45.

The pintle sockets are all elongated, and the bearing edges are inclined as seen at Figs. 5 and 8. These features are important, the elongated sockets permitting the pintle and sash to change position while the sash is swinging, and thus to avoid interference by the back corner of the sash with the window frame when the sash is swung to its closed position. In this manner I render unnecessary the beveling oif of the corner of the sash, and the inclination referred to of the bearing edges tends to make the shifting of the sash automatic. I prefer to arrange the sockets so that their elongated lines shall stand at right angles to each other.

It .will be understood that the construc tion shown permits both sashes to be swung by lowering them to the lower part of the window, shifting the sockets of the lower sash, removing the stops and detaching the weight cords from the swinging side of the sash. hen thus swung the glass of both sashes can be washed conveniently by a person standing upon the floor.

I claim 1. The combination with a hinged window, of a stationary pintle upon the window frame, a horizontally movable socket upon the sash adapted to engage said pintle, a plate carrying the socket, a keeper having its upper and lower edges bent over and confining the socket plate, and a locking projection on the plate engaging the turned over edge of the keeper.

2. The combination with a hinged window, of a stationary pintle upon the window frame, a horizontally movable socket upon the sash adapted to engage said pintle, a plate carrying the socket, a keeper having its upper and lower edges bent over and confining the socket plate with suflicient freedom to permit vertical movement in locking and unlocking, and a locking projection on the plate engaging the turned over edge of the keeper.

3. The combination with a hinged window, of a stationary pintle upon the window frame, a horizontally movable socket upon the sash adapted to engage said pintle, a plate carrying the socket, a keeper having its upper and lower edges bent over and confining the socket plate, a spring pressing against the edge of the plate, and a locking projection on the plate engaging the turned over edge of the keeper. 4

4. The combination with a hinged window, of a stationary pintle upon the window frame, a horizontally movable socket upon the sash adapted to engage said pintle, a plate carrying the socket, a keeper having its upper and lower edges bent over and confining the socket plate with sufficient freedom to permit vertical movement in looking and unlocking, a spring pressing against the edge of the plate, and a locking projection on the plate engaging the turned over edge of the keeper.

5. The combination with a hinged window, of a stationary pintle upon the window frame, a horizontally movable socket upon the sash adapted to engage said pintle, a plate carrying the socket, a keeper having its upper and lower edges bent over and confining the socket plate, and a locking projection on the plate engaging both a notch formed in the turned over edge of the keeper and the end of said edge.
